Why did my tracks disappear?
To fix the file location issue I did: Outliner &gt; change the &quot;display mode&quot; to &quot;Data API&quot; instead of &quot;View Layer or &quot;Scene&quot; &gt; scroll down to Movie Clips and in there I found the file paths from Movie Clip and Movie Clip.001 and just copy/pasted Ctrl+C / Ctrl+V the correct file path.
Still not sure how to fix the deleted solve data/track data.
Best I can tell is shift-clicking the X for the Movie Clip data block (deleting the false user) and then saving the blend file permanently deletes the solve/track data and the clip must be re-tracked and re-solved.  &quot;Ten four rubber ducky. Over and out.&quot;
